How this service works
Browse the Federal Reserve FRED category tree to DISCOVER economic series. Pass a categoryId to get that category (name + parent), its child categories, and the most-popular series filed under it (id, title, units, frequency) — then pull the data with econ.fred. Omit categoryId (or pass 0) for the eight top-level categories: Money/Banking/Finance, Population/Employment/Labor, National Accounts, Production & Business Activity, Prices, International Data, U.S. Regional Data, Academic Data. Walk down via each child's id. Free, public-domain (FRED). The structured map of what FRED actually contains — far more reliable than guessing series ids. Companion to econ.fred (fetch/search) and econ.fred-releases (calendar).
Output
Returns a list of FRED categories (with IDs, names, and parent relationships) along with up to the requested number of economic data series belonging to the specified category, drawn from the Federal Reserve Bank of St. Louis FRED database.
